Is there a commutative property of subtraction that states a-b=b-a? investigate and make a conclusion that you justify.
Rom4ik [11]

No is your answer

Assuming that b ≠ a, the answers will not be the same.

For example, (remembering that b ≠ a) let us assume that b = 10, a = 5

10 - 5 = 5

5 - 10 = -5

5 ≠ -5

So the commutative property of subtraction does not work unless in certain cases, in which a = b.

hope this helps

The radius of Venus is 3,760.4 miles. What is the approximate volume of Venus?
sdas [7]
The radius of a sphere is calculated through the equation,
                             V = 4πr³ / 3
where r is the radius. Substituting the radius given in the equation,
                            V = 4π x (3,760.4 miles)³ / 3 = 2.23 x 10^11 miles
Thus, the volume of the planet Venus is calculated to be 2.23 x 10^11 miles, approximately.
